论文摘要
我们研究了网格和QUDA库中可用的最先进的兰开斯元素。其中包括隐式重新启动的兰努斯斯，厚实的兰斯佐斯和阻塞兰开斯。我们为高度改进的交错夸克（HISQ）DIRAC操作员测量和分析其性能。我们还讨论了Chebyshev加速度的优化。
We investigate the state-of-the-art Lanczos eigensolvers available in the Grid and QUDA libraries. They include Implicitly Restarted Lanczos, Thick-Restart Lanczos, and Block Lanczos. We measure and analyze their performance for the Highly Improved Staggered Quark (HISQ) Dirac operator. We also discuss optimization of Chebyshev acceleration.
